Gene Information

human ... THPO(7066)

General description

Thrombopoietin (TPO) is a lineage specific growth factor, produced in the liver, kidney and skeletal muscle. It is an acidic glycoprotein. The gene encoding it is localized on human chromosome 3q27.1. Recombinant human TPO is a fully biologically active 174 amino acid polypeptide (18.6kDa), which contains the erythropoietin-like domain of the full length TPO protein.

Biochem/physiol Actions

Thrombopoietin (TPO) stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals through the cellular proto-oncogene (c-mpl) receptor and acts as an important regulator of circulating platelets. High levels of TPO have been observed in patients with aplastic anemia. Human and murine TPO exhibits cross-species reactivity.

Physical form

Lyophilized from 0.1% TFA.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C.

Most hematopoietic stem cell gene therapy studies require host conditioning to allow for efficient engraftment of gene-modified cells. Conditioning regimens with lower treatment-related toxicities are especially relevant for the treatment of nonmalignant blood disorders, such as hemoglobinopathies and immunodeficiencies, and

We recently identified 2 siblings afflicted with idiopathic, autosomal recessive aplastic anemia. Whole-exome sequencing identified a novel homozygous missense mutation in thrombopoietin (THPO, c.112C>T) in both affected siblings. This mutation encodes an arginine to cysteine substitution at residue 38 or
